The interface unit 150 is able to transceive signals with the spaceremote controller 201 through the RF module 152 by wireless. And, theinterface unit 150 is able to receive a signal transmitted by the spaceremote controller 201 according to the IR communication specificationsvia the IR module 153.

The display module 155 partitions a portion of a whole screen of thedigital broadcast receiver 100. Each of the control regions correspondsto each unique function of the digital broadcast receiver 100 and ascreen remote controller is displayed on the corresponding controlregion.

The wireless communication unit 151 or a receiving module (not shown inthe drawing) receives a pointing signal from the space remote controller201.

The determining unit 156 determines whether the received pointing signalis recognized in a range within a specific control region within thedisplayed screen remote controller.

If the received pointing signal is recognized to be in the range withinthe specific control region, the control module 157 controls a specificfunction, which corresponds to the specific control region among uniquefunctions of the digital broadcast receiver 100, to be activated.

Furthermore, the display module 155 is able to display both the controlregion and the summary of each of the functions corresponding to thecontrol region simultaneously.

If the received pointing signal remains relatively still or has mobilityin the range within the specific control region within the displayedscreen remote controller, the determining unit 156 can regard receivedpointing signal as being in the range within the specific controlregion. While the received pointing signal is located in the rangewithin the specific control region within the displayed screen remotecontroller, if a specific button signal (e.g., an ‘OK’ button signal) isapplied, the determining module 156 is able to regard received pointingsignal as being in the range within the specific control region. Forinstance, if the pointing signal remains still in the control regionindicating Channel 9 during about 3 seconds or moves within the controlregion only, an operation command signal for tuning to Channel 9 isgenerated.

Each unique function of the digital broadcast receiver can correspond toinformation on at least one of a channel number, a volume level andgenre setting. Therefore, according to one embodiment of the presentinvention, using the above described space and screen remotecontrollers, a conventional remote controller configuration can befurther simplified. And, numerous channels and functions of digitalbroadcasting can be controlled more easily.

Meanwhile, according to another embodiment of the present invention, thecoordinates calculating unit 154 corrects handshaking or error from asignal, which is received via the wireless communication unit 151,corresponding to the motion of the space remote controller 201 and isthen able to calculate a coordinates value (x, y) of a cursor 202 to bedisplayed on the display 170.

A space remote controller 201 transmission signal inputted to thedigital broadcast receiver 100 via the interface unit 150 is transmittedto the control unit 180 of the digital broadcast receiver 100 shown inFIG. 1. The control unit 180 shown in FIG. 1 determines information on amotion and key manipulation of the space remote controller 201 from thesignal transmitted from the space remote controller 201 and is then ableto control the digital broadcast receiver 100 to correspond to thedetermined information.

Furthermore, according to a further embodiment of the present invention,the space remote controller 201 calculates a cursor coordinates valuecorresponding to the motion of the space remote controller 201 and isthen able to output the calculated cursor coordinates value to theinterface unit 150 of the digital broadcast receiver 100. In this case,the interface unit 150 of the digital broadcast receiver 100 is able totransmit the received information on the cursor coordinates value to thecontrol unit 180 without separate handshaking or error correction.

Also, according to another embodiment of the present invention, thedisplay module 155 displays the trace of the pointing signal receivedfrom the space remote controller 201 continuously. In case ofdetermining that a character corresponding to the displayed trace of thepointing signal exists based on a stored character recognition rule, thedisplay module 155 displays a broadcast list related to the character.In this case, the broadcast list can include at least one item selectedfrom the group consisting of a channel number including the characterand a program including the character.

For instance, if the character corresponding to the displayed trace ofthe pointing signal is ‘3’, it is able to display the broadcast list ofchannel numbers containing the character ‘3’ such as ‘3’, ‘31’, ‘33’,‘39’ and the like. For another instance, if the character correspondingto the displayed trace of the pointing signal is ‘new’, the device isable to display the broadcast list of programs containing the character‘new’ such as ‘9 O'clock news’, ‘MMM news’, ‘Economy news’ and the like.

FIG. 6 is a flowchart for a method of controlling a digital broadcastreceiver controlled by a space remote controller and a screen remotecontroller according to one embodiment of the present invention.

In one embodiment,one may design the step S601 to simultaneously display the controlregion and a summary for each function corresponding to the controlregion. And, each unique function of the digital broadcast receiver cancorrespond to at least one selected from the group consisting of achannel number, a volume level and information on genre setting forexample.

A pointing signal is received from a space remote controller [S602].Subsequently, it is determined whether the received pointing signal isrecognized in a range within a specific control region within thedisplayed screen remote controller [S603]. Meanwhile, for instance, ifthe received pointing signal remains still or if the received pointingsignal has mobility in the range within the specific control regionwithin the displayed screen remote controller, the step S603 recognizesthe received pointing signal to be in the range within the specificcontrol region.

If the received pointing signal is recognized in the range within thespecific control region, a specific function corresponding to thespecific control region (among unique functions of the digital broadcastreceiver) is controlled to be activated [S604].

Referring to FIG. 7, a digital broadcast receiver according to oneembodiment of the present invention has a character recognition rulestored in a memory [S701]. In this case, the character recognition rulemay be a technique for automatically recognizing an image figurerandomly marked by a user or the like as a character intended by theuser or the like. The character recognition may follow a conventionalcharacter recognition rule. Alternatively, one embodiment of the presetinvention can be implemented according to a following process as well.

The digital broadcast receiver receives an input of a pointing signalfrom a space remote controller [S702] and then checks a coordinatesvalue of the inputted pointing signal [S703]. And, the digital broadcastreceiver determines whether a character corresponding to a tracedisplayed according the checked coordinates value exists [S704].

As a result of the determining step S704, if the corresponding characterdoes not exist or is not recognized, a previously searched broadcastlist is displayed [S705]. On the contrary, if the charactercorresponding to the trace is recognized, a broadcast list including theexisting character is displayed [S706]. In displaying the broadcastlist, the device is able to use a channel number or broadcast side dataprovided by EPG or the like.

Accordingly, in a broadcast receiver according to one embodiment of thepresent invention, a method of controlling a broadcast receivercontrollable by a screen remote controller includes the steps ofdisplaying a screen remote controller partitioning a portion of a wholescreen of the broadcast receiver into at least two control regions,displaying a cursor to enable a first pointing signal outputted from thespace remote controller to indicate one control region of the screenremote controller, receiving a second pointing signal from the spaceremote controller, and executing a function corresponding to the onecontrol region indicated by the cursor. In this case, the secondpointing signal can correspond to a confirm command signal for executingthe function corresponding to the control region.

A method of controlling a broadcast receiver according to anotherembodiment of the present invention includes the steps of receiving asignal for changing a mode of the broadcast receiver and displaying ascreen remote controller corresponding to the received mode based on thereceived mode. In this case, the mode includes at least one of a modefor executing a DVD function, a mode for executing an internet functionand a mode for executing a photo editing function.

Moreover, the function corresponding to the control region correspondsto at least one of channel up/down, channel number, sound up/down andinformation on genre setting. The broadcast receiver can further displayinformation indicating a function mapped by the control region on thecontrol region. The broadcast list includes at least one of a channelnumber corresponding to the displayed trace and a program titleincluding a character.

The broadcast receiver includes a digital broadcast receiver. And, thedigital broadcast receiver includes at least one of an IPTV (internetprotocol TV) and a BBTV (broadband TV).
